do. >> reporter: dr. john sanjay gupta, cnn, reporting. intse pa. it progressively got worse. my rheumatologist told me about enbrel. i'm surprised how quickly my symptoms have been managed. [ male announcer ] because enbrel suppresses your immune system, it may lower your ability to fight infections. serious, sometimes fatal events including infections, tuberculosis, lymphoma, other cancers, and nervous system and blood disorders have occurred. before starting enbrel, your doctor should test you for tuberculosis and discuss whether you've been to a region where certain fungal infections are common. don't start enbrel if you have an infection like the flu. tell your doctor if you're prone to infections, have cuts or sores, have had hepatitis b, have been treated for heart failure, or if, while on enbrel, you experience persistent fever, bruising, bleeding, or paleness. get back to the things that matter most. good job girls. ask your rheumatologist if enbrel is right for you.
